ANCHORING MEANS.-

Application filed July 29,

for guyfropes, anchor rings or like devices for holding marine or air craft.

The objects of the present'invention are to provide simple and eflicient anchoring means capable of being produced at a comparatively lowcost of manufacture, to enable theanc'horing device to be screwed into the ground to any desired depth, and to insure that the device; anchored to the .ground cannot be removedwithout great difliculty. According to this invention the fixture to be anchored to the ground is attached to the one end of a wire rope, chain or a metal rod of the desired length and to the opposite end of this rope or rod is attached a pile screw. The pile screw is adapted to I receive a detachable hollow shank whereby the pile screw is screwed into the ground to the desired depth and then the hollow shank is removed, leaving the pile-screw and the wire rope or metal rod buried in the ground as a permanent fixture.

The accompanying drawings illustrate the application of the present invention, by way of example to fixing a boundary-mark or other land-mark.

' Figure 1 is a perspective view illustrating the boundary mark or other land-mark in its fixed condition.

Fig. 2 is a view in side elevation and Fig. 3 a view in vertical section of the pile screw.

Fig. 4 isa sectional view of a modified construction of pile screw.

Fig. 7 is a view in side elevation.

Fig. 8 a vertical section and Fig. 9 a plan view of the cap which is secured to the pile head. 1

screw A is constructed with 1 preferably tapered towardits lower end and around the body portion is. a screw thread or helix 2. The tapered portion of the body may be'hollow and be cut awayfat the end insuch a manner as to form a point ed end .3 triangular in shape. as shown in F lgs. 2 and 3 or the body'portion may be solid as shown in F ig.4. The upper end of the bodyportion has secured thereto in any suitable manner-one'end of wire rope B or a chain or a metal bar the length of which corresponds with the depth the pile screw A is to be inserted into the ground. The other end of this wire'rope, chain. or bar, is at tached to a pile head C composed'of metal in the form of a rod with square or buttress threads 4 thereon terminating at the outer.

end thereof in a head 5 adapted'to receive a key or box spanner. fitted a'meta l cap 'D form of a hollow cone or other desired shape the base 6 of which is formed with a corresponding projection 7 to screw on to the pile head C or. the connection may be made by means of a bayonet joint or the like. The top of the cap is open and holes may be formed in the wall of the cap throughiwhich bars are passed to screw the cap on to the pile head, but by preference the cap is formed with lugs 8 which are engaged by a spanner to turn the cap.

The pile screw A is screwed into the ground by means of a tube 9 (Fig. 10) through which the pile-head and wire-rope are passed and then the lower end of the tube is engaged with the upper end of the pile screw. A lever or levers 10 is or are now attached to the tube 9 and the latter thereby turned to force the pile-screw A into the ground to the extent of the length of the wire rope B. This having been done the tube is removed and, as shown in Fig. 11 a block E of concrete or a stone slab with a central hole 11 is now placed over the pile head C with a portion of the latter projecting through the hole and above the face 7 of the concrete or stone to receive, the cap D.

The base of this cap is then screwed on to the pile-head as shown in Fig. 12. This is effected by means of a box-spanner 12 which is passed through the opening in the top of thecap D and placed over the upper end of the pile-head. This head is now held while the cap D is screwed thereon by means of a spanner 13 which engages the lugs 8 a body portion On this pile head is" whichmay' be in'the formed on the Walls 01. the cap. The cap D having been screwed down on to the concrete block E the interior of the former is then filled with cement which serves when set to bind the cap and the concrete block together.v r

The boundary mark or the like thus constructed being anchored at a depth below the surface of the ground cannot readily be removed, and it will also be seen that the elements employed are simple in construction, convenient for transport and the labor reluired to fix the boundary mark is comparatively'light.

It'will belobviou s that theinvention above described applicable to fixtures other than bbundai markets apparatus similar to a cribed may be consume in a ma neraaapedto ave as a h ring m a f Whatever purpose desired, either on land or beneath the surface of Water, or the apparatus may be adapted for use as a bench mark insurvey agma is to say a fixture on the ground, the height of which above sea level is known.

i In some cases the employment of a hollow cap ay be dispensed with and the pile screw inserted into the ground to such a depth as to bury or partially bury the pilehead, which may be of any desired construction according to the purpose for which it is intended to be used. For example as shown in Fig. 13 the end of the rope B is formed with an eye B to receive a shackle or the like.

hat I claim as my invention and desire to secure 'by'Letters Patent is 1. Anchoring means comprising a pile screw adapted to be screwed into the ground, a pile head, means for connecting the pile head to said pile screw, a slab adapted to be arranged about the pile head, ahollow cap secured over the pile head above the slab and a cement filler in the cap to bind thepile head andslab. together, substantially as described. I

2. Anchoring means comprising an anchor adapted tobe' embedded in the ground, a head adapted to rise from the surface level of the ground, means connecting the anchor to said head, a slab adapted to be arranged on the surface of the ground about said head, a hollow cap secured to the head and bearing upon said slab, and a body of binding material arranged in the cap for securingsaid head and'slab together, substantiallyas described. j
